Song translation

Hello,

I'd like to translate the song "What a feeling" of Irene Cara and
I need precisions.

In the sentence:
"Well, I hear the music
Close my eyes, feel the rhythm
Wrap around, take a hold
Of my heart."
what is the meaning of "take a hold"?

In the sentence:
"Take your passion
And make it happen
Pictures come alive, you can dance right through your life"
can "Pictures come alive" be express by "Dreams become reality"?
And in "right through your life", what is the meaning of "right", is it separable from "through"?

In the sentence:
"Now I hear the music
Close my eyes, I am rhythm
In a flash it takes hold
Of my heart"
what is the meaning of "In a flash?
Does it mean "In no time", "Very quickly"?

Have a good day.
Thank you.
